Hello and welcome to VanillaMod

Unfortunately your first point cannot be done as it requires Kingdoms. I have vowed that this mod will never require Kingdoms so all those non Kingdoms players have a mod they can have fun with that is up to the standard of other Kingdoms mods.

I have been considering including the CNP, but finneys has been rather uncooperative with fixing bugs in his mod (CTD and missing names) or providing more information on it, so its currently out until that situation changes.

Not aware of diplomacy text bugs but then I hardly ever read them. Let me know when you get them (i.e. with which faction, talking to which faction about what and their response) or a rough outline of what was said so I can track it down and fix it.

Aging characters 1 year per turn is only possible by making the campaign stay always in winter mode, so that is not really a great option sadly
